The present invention refers to a process for oligomerization of acetylene in the presence of hydrogen and a solid catalyst.

A catalyst and a process for using the catalyst are presented. The catalyst is a heterogeneous catalyst and includes active metal halides bonded to functional groups. The functional groups are bonded to a polymeric backbone to form the structure supporting the catalyst. The catalyst is useful for the dimerization of acetylene to convert the acetylene to a larger hydrocarbon, and in particular to dimerize acetylene to vinylacetylene.

A system and a process for dimerizing cyclopentadiene (CPD) including producing a C.sub.6+C.sub.7 rich bottoms stream and a C.sub.5 rich side draw from a debutanizer, where the C.sub.5 rich side draw and at least a portion of the C.sub.6+C.sub.7 rich bottoms stream are directed to a dimerizer where the CPD is thermally dimerized to dicyclopentadiene (DCPD). DCPD is more stable than CPD and thus safer to handle.

A process for making high density fuels, pure terpene dimers, and byproducts from mixed terpene feedstocks and the resulting high density fuel products. The fuels produced by the process includes, dimerizing at least one terpene feedstock by mixing at least one terpene with at least one heterogeneous acidic catalyst and at least one solvent used to control the reaction temperature for a desired time and temperature to produce a crude terpene dimer (C.sub.20H.sub.32 mixture) in about 65% to about 95% chemical yield, hydrogenating the crude terpene dimer (C.sub.20H.sub.32 mixture) with at least one hydrogenation catalyst under a hydrogen atmosphere and removing the hydrogenating catalyst(s) to produce about 65% by weight to about 95% by weight of hydrogenated terpene dimer mixture, and utilizing a separation method against the hydrogenated terpene dimer mixture to produce byproducts, where the process generates a hydrocarbon mixture with a viscosity of between about 20 and 50 cSt at 40 C.
